The rod 11 is ar ranged adjacent to .one of the edges of the member 7, both the said rods having their ends passed outwardly through the asbestos .sheet end through'the outer. facing of the wire mesh and one of. the said pro'ecting ende of each of the said rode 10 and 11 v1s bent upon itself to provideeyes 12 and -13 respect-.1v The'o posite ends of-th'e rods rovidew tIwill' termtonguesendare indicated by the characters 14 and 15 reepectively.

Ihe member 7 is of e length to surround 110 the tank and thecloeure for thetank and to pennit of its ends lapping around both through the eyes to tigh y member 7 around the under-edge o the cor. nice and around the tank 1 below the cement '.jcepeble of resisting the tt acids, it will be noted that I 'have' rovded j e simple, cheap and eeient me odand the tankend the closure.

AThe upper edge of the member 7; 'that is,

the edge thereof o posite that rovided with the wire or rod 1 is arranged around the edge of the to I '5 or closure '4; es illustrated in Figs. 1 en i 3 of thedrewin and secured to the said top or closure -neils 17,4 the heads of the seid nails being protected by the cemeut 6.A The wires or rods 10 end 11 then 10 have their ends which I have termed the 6, below the cornice, the tongues being then bent over the eyes and over the rods or wires from which they are formeds illustrated in Fig. 1 of the drawing. e member 7 .is designed not only to protect the cement 6 et they joint between the tank und the top therefor, but is also in the nature of an electric 'conductor and is designed to protoet and ground thetenk electricallly, should' theseme be charged. with static e ectrcity. 1 Thecexnent or sie composition 6 is a. non-conductor'of .electricity and the mem- 31) ber?, in the rocess .of manufacture, is ren- 'deredsoft an liable so that the seme may `\fbe. eesily e Aedto the roof end'to the oil tenks iprmarily ceusedv the electricd currents Awhontank is with static' electricity ium ingI from one motel to enothcnm esfgelilinemher 'I is a. conductor of electricity y iii-'liso composed of nonio inil'ammnble r'efneterding materiel, the

Hoving t us described the invention, what I claim is: Y

1. In combination with e metallic tank for` aseous fluids, having e. cornice receiving e metallic cover thereof and e plastic cement of iirse-reterdn'g,r4 ges and acid resisting non-electric `conducnng mnterial arranged between the cornice andthe cover of the tank, of a. bindin element for retaining such plastic histeria. V onfthetctnk seid binder surrounding the outerfed'ge of the cover :md the cornice of the tank end mede up of e wire mesh, e sheet of asbestos associated with the mesh, ond e coating of preservative electric conducting material, rod members passing throu h seid binding, eyes on the ends of the s and seid eyes designed .to receive the opposite ends of the rods',` whereby said last mentioned ends may be bent upon themselves to effect in retaining the sheathing upon the tank.'-

2. In 'combination with e metallic storage tank for gaseous fluids, including n. cover extending over the mouth of the tank, and e plastic cement arranged between the cover and the outer end of the tank, of a binder said plastic material against the tank, comprising a, wire storage mesh centrally bent upontself to provide inner and outer faces a. sheet of fire proof meterialbetween seid feces, a coa of reservetive electric conducting materia. for e binder,` spaced wire rods`extending lengitudinelly between the faces of the binder, eyes on one of the ends of each rod, tongues onthel other end of seid tongues designed to be received 1n the said eyes wher-eb to compress the binder against the tank en to eifect in retaining the said binderon the tank.
